High-spin states in 179Au : Spectroscopy of shape-driving orbitals beyond the neutron midshell
Abstract
Multiple band structures in 179Au are established from γ -ray spectroscopic measurements with Gammasphere at the Argonne Fragment Mass Analyzer. The yrast band, based on the 13/ 2+ proton, confirms the predicted drop in excitation energy of the prolate deformed band head as compared to the heavier isotopes. The implications for the prolate energy minimum in odd-mass Au nuclei beyond the neutron i13/2 midshell (N<102) are discussed.
